He tells the Detroit Free Press: "I think the band needs to have a unified concept of what Aerosmith is to our fans. Without trying to pander and do market research, we need to get closer to understanding our history and the band that the world wants Aerosmith to be.

"I think it's a combination of the stuff we did in the 70s when we really started learning the studio, like the Toys In The Attic album and the Rocks album, and then some from the later era of the band, when we did Pump and Permanent Vacation. I think those albums describe what this band is about musically."
